a - UNS numbers beginning with an “N” indicate a nickel alloy, but the definition of a nickel alloy is different than that used by ASTM.

b - in ASTM specifications, most nickel alloys fall into the “B” specifications. However, due to a redefinition of a nickel alloy, a few alloys such as 800 and 20 are being reclassified as stainless steels and will be included in the “A” specifications. That work is still in progress.

c - the 6%Mo alloys are a series of stainless steels, many of which are proprietary, all with roughly 6%Mo content and roughly equivalent in performance.

d - the austenitic stainless steels with high Si are proprietary and were developed from nitric acid grades for use in strong sulphuric acid.


The most common grades are TP 304 and TP 316. Grades TP 304H, TP 304N, TP316H, TP316N, TP321H, TP347H and TP348H are modifications of Grades TP 304, TP 316, TP 321.Grades TP 347 and TP 348 and are intended for high-temperature service.


Grades TP304H, TP309H, TP309HCb, TP310H, TP310HCb, TP316H, TP321H, TP347H, and TP348H are modifications of Grades TP304, TP309Cb, TP309S, TP310Cb, TP310S, TP316, TP321, TP347, and TP348, and are intended for service at temperatures where creep and stress rupture properties are important.


These pipes are used in the process, petrochemical, pharmaceutical, and food industries.
